Taxonomic revision and reclassification of Pseudolinosyris with related taxa in Galatella (Asteraceae)

The taxonomic position of Pseudolinosyris is revised. The genus is reduced to Galatella sect. Pseudolinosyris (Novopokr.) Scnnikov comb. nova. It differs from the other sections by its shorter corolla lobes and a higher level of stem lignification. Two species are recognised in this section: G. grimmii (Regel & Schmalh.) Sennikov comb. nova, with three subspecies including G. grimmii subsp. microcephala (Novopokr.) Scnnikov comb. nova and G. grimmii subsp. simenisii (Bornm.) Scnnikov comb. nova. and the newly added G. corymbulosa (Bornm.) Sennikov comb. nova. A further species is transferred from Crinitaria to Galatella, G. a.sperella (Rech. f. & Koie) Sennikov, comb. nova to form a monotypic section Galatella sect. A.sperilbliae Sennikov. sect. nova. All the species and subspecies are redescribed and mapped. and their complete synonymy with typifications and a new identification key are provided.Peer reviewe
